Objective: To understand the clinical manifestation, imaging characteristics and outcomes of pulmonary malignant tumors in children. Method: We retrospectively collected information about seven cases of pulmonary malignant tumors in children in our hospital from Jan 2010 to Dec 2016. The information included clinical manifestation, imaging characteristics, pathologic results, and treatment. Result: (1) All the seven patients firstly visited pediatric internal medicine departments. Symptoms included cough (n=6), dyspnea (n=4), fever (n=2), anorexia (n=2), chest tightness (n=1), chest pain (n=1), lameness (n=1), abdominal distension and constipation (n=1)...

BACKGROUND/AIM: The treatment of patients with solitary hematogenous metastases from non-small cell lung cancer (NSCLC) remains controversial, although numerous retrospective studies have reported favorable results for patients offered combined surgical therapy. Our aim was to determine the role of surgical resection in the management of NSCLC with solitary extrapulmonary metastases and to investigate for possible prognostic factors. PATIENTS AND METHODS: Between January 2004 and December 2012, 12 patients with NSCLC, from two Institutions, underwent metastasectomy for their solitary metastatic lesion...

Hybrid lesions (HLs) have elements of congenital pulmonary airway malformation and extrapulmonary sequestration (EPS) and belong to the congenital lung lesions. EPS usually arises in the thorax or the abdomen but rarely in the diaphragm. The preoperative diagnostic work-up based on chest radiograph, ultrasound (US) and CT often shows imprecise results. Therefore, the exact localisation of the lesion can only be ascertained intraoperatively. Here we present a patient, with an intradiaphragmatic HL, and demonstrate the difficulties of surgical decision making regarding the localisation of the lesion and discuss the value of minimal invasive surgery...

Although Mycobacterium tuberculosis (M.tb) DK9897 is an attenuated strain, it was isolated from a patient with extrapulmonary tuberculosis and vaccination with a subunit vaccine (H56) induced poor protection against it. Both attenuation and lack of protection are because M.tb DK9897 cannot secrete the EsxA virulence factor nor induce a host response against it. Genome sequencing identified a frameshift mutation in the eccCa1 gene. Since the encoded EccCa1 protein provides energy for ESX-1 secretion, it suggested a defect in the ESX-1 type VII secretion system...

Tuberculosis (TB) mortality rates in the USA fell rapidly from 1910 to 1933. However, during this period, racial disparities in TB mortality in the nation's expanding cities grew. Because of long delays between infection and disease, TB mortality is a poor indicator of short-term changes in transmission. We estimated the annual risk of TB infection (ARTI) in 11 large US cities to understand whether rising inequality in mortality reflected rising inequality in ARTI using city-level TB mortality data compiled by the US Department of Commerce from 1910 to 1933...

BACKGROUND: Nosocomial pneumonias are common in trauma patients and so interventions to prevent and treat nosocomial pneumonia may improve outcomes. Our prior work strongly suggests that tissue injury predisposes to infections like nosocomial pneumonia because mitochondrial debris originating from injured cells contains damage-associated molecular patterns that can reduce neutrophil (PMN) migration into the airway and diminish PMN function in response to bacterial inoculation of the airway...

REVIEW
Michael K Leonard, Henry M Blumberg
Musculoskeletal tuberculosis (TB) accounts for approximately 10% of all extrapulmonary TB cases in the United States and is the third most common site of extrapulmonary TB after pleural and lymphatic disease. Vertebral involvement (tuberculous spondylitis, or Pott's disease) is the most common type of skeletal TB, accounting for about half of all cases of musculoskeletal TB. The presentation of musculoskeletal TB may be insidious over a long period and the diagnosis may be elusive and delayed, as TB may not be the initial consideration in the differential diagnosis...

Tuberculosis (TB) and sickle cell anaemia (SCA) may affect the same population of patients, particularly in Africa but also in high-TB incidence areas in developed countries. However, few data are available from children with SCA who develop TB. The aim of this study was to describe the clinical features and outcome of TB diagnosed in children with SCA. We conducted a retrospective, descriptive study in three referral centre of Sickle Cell Disease in Paris, France. We included 11 patients with SCA who develop TB...

BACKGROUND: Nontuberculous mycobacteria (NTM) were considered saprophytic organisms for many years but now are recognized as human pathogens. Although humans are routinely exposed to NTM, the rate of clinical infection is low. Such infections usually occur in the elderly and in patients who are immunocompromised. However, there has been an increasing incidence in recent years of infections in immunocompetent hosts. NTM infections in immunocompetent individuals are secondary to direct inoculation either contamination from surgical procedures or penetrating injuries rather than hematogenous dissemination...

The collectin surfactant protein‑A (SP‑A), a potent host defense molecule, is well recognized for its role in the maintenance of pulmonary homeostasis and the modulation of inflammatory responses. While previous studies have detected SP‑A in numerous extrapulmonary tissues, there is still a lack of information regarding its expression in central nervous system (CNS) and potential effects in neuroinflammatory diseases, such as multiple sclerosis (MS). The present study used experimental autoimmune encephalomyelitis (EAE), the most commonly used animal model of MS, to investigate the expression of SP‑A in the CNS at different stages of disease progression...

A 28-year-old female patient presented through her primary care physician with symptoms of atypical chest pain and chronic cough. Her pain was described as pleuritic and intermittently radiating to the right arm. Her medical history was significant for recurrent respiratory infections, gastritis, and a left ovarian cyst treated with ipsilateral salpingo-oophorectomy. She denied any history of smoking, known lung disease, or extrapulmonary infections.

Urogenital tuberculosis (UGTB) is the most common form of extrapulmonary TB and is responsible for a destructive inflammation of the renal parenchyma and urinary tract often leading to the loss of kidney function. For these reasons, the early diagnosis of this disease, once considered disappeared in developed countries, is very important to establish a prompt and efficient treatment. However, the subtle and non-specific symptoms, often represented by recurrent and persistent lower urinary tract symptoms, can confound and delay the diagnosis...

BACKGROUND: One of the rare presentations of active pulmonary or even extrapulmonary tuberculosis is polyarthropathy which is the involvement of multiple large and small joints in the body; a reactive constellation known as Poncet's disease. This may sometimes be the sole manifestation of the disease before more obvious features develop. The pain experienced during polyarthritis can be crippling thereby limiting the mobility and activities of patients. Polyarthritis as a symptom of active tuberculosis can be easily misinterpreted for more common causes of polyarthritis such as rheumatological diseases that present similarly...

Intramedullary spinal tuberculoma is an extremely rare disease when compared to pulmonary, extrapulmonary and skeletal tuberculosis in developing countries. In the absence of systemic tuberculosis, clinical presentation is non distinctive from other intramedullary lesions. We report two cases of intramedullary tuberculoma both presenting with signs and symptoms of space occupying lesions. Surgical excision was done in both cases following which patients improved neurologically. Histopathological evaluation is essential to provide curative treatment...
